They are in front of the elevators at an outdoor multi story parking garage around my area. That's all I wanted to share, thanks.

I don't think that's how radiant heat transfer works. Should generally heat anything colder than the heat source

    Kinda both right, it heats surfaces the infrared energy emitted by the heater can make contact with. It won’t heat open air which makes it extremely useful in outside environments or anywhere with a potential for airflow. But yeah it does heat everything it does point at, just not the air in between. Really useful for heating furniture to heat the ambient area in addition to the people present.
